Probabilistic Causality from Graviton Fluctuations
Giordano Cintia, Federico Piazza, Samuel Ramos
We compute the commutator of a scalar field minimally coupled to gravity at leading order in . The commutator is operator-valued, with terms involving derivatives of Dirac del…

Relativity of the event: examples in JT gravity and linearized GR
Francesco Nitti, Federico Piazza, Alexander Taskov
Observables in quantum gravity are famously defined asymptotically, at the boundary of AdS or Minkowski spaces. However, by gauge fixing a coordinate system or suitably dressing th…
